To all whom it mayyconcm:

Be it known that I, HI'RAM H.W1SE, a citizen of the -United States, andfresident .of-

Decatur, in the county ofMacon and'State of.

Illinois, have`invented certain newand use- .4 ful Improvements inCisterns'; and my pre ferred manner of carr in out -the invention is setforth in the fol owing full,` clearfand exact description, terminating with claims particularlyspe'cifying the novelty.

l.. This .invention relates'to masonry, and

more especially to that class of 'devices there?" under known as cisterns; and the object of the same is to so construct a cisternv that it. may be cleaned -Without first completelyy and prefera ly also separating these two' portions of the cistern by'a filter Wall-all as ereinafter more ullyfdescrib'ed and claimed and as shown in theV accompanying drawings Where'ln- Figure 1 isav central vertical 'section 'of this.

' Referring to' the drawings by letter, W designates vthe Wall of this' cistern having a mouth M, B` the b ottomthereof, and R a raised ortion of said bottom which, asse'en,l

is on a' igherflevel thanthe truefbjottom and f 'by' preference is substantially fiat orI level'so the operator can stand thereon, 'and occupies about half of the Iiiameter of the cistern althou h -this proportion-.is 'not necessary; The etter I designates the inlet, and O. is the outlet, the lattertaken from apoint dee in the depressed portion of the bottom. ithl l a cistern 'as thus constructed, the inlet Water y flowing in at .I s'trikes'thev raised bottom R depressed portion of the bottom, from which it 1s drawn through the outlet O. It will be obvious that what sediment'of heavier articles flows into the cisternwillfrest an aecumulate upon the v raised bottom, While possibly*` the lighter particles 'or'. impurities will over 'the angle and falfjinto :the storage Waterl and befvdrawv out the outlet'.

Nevertheless, in order to clean this cistern it .'56 .is only necessary. to draw 'ofi Water to 'about' the level indicatedili Fig. l, afterwhich the* operator can getinte thecisteriibodily .'ziioi-` ing the'cistern is as above', excepting that the',

'standing on-the'raisedportion R can 'olea "of it'thel larger p'art o the accun'rula'tio dirt which rest thereon. In fthev profe .construction of this cistern, however, Ibuildy a yperforated wall P `rom. fthe angle' .tween-the raised andtrue-bottom obliquel' 'upward aboutl as shown in lFig.Y vI, .thereby dividing I the 'cistern -ingo twdspees .U and F. Within the foriner will accumulate'liiil' -tere'd water, and, passing througlrtheper-tl 'i' vlvorated or filter Wall lPtg'within t avill accumulatel th'e iiltered'wa'ter-W icl11iswithdrawn through the outlet yOJ It vtli'roiiflgfh 4the inletl thewater level will 4 higher than indicated in 1.` andWill-st'and, `upon thefraise'd' portion R aswell as above the depressed portion Blof the bottom, 'r Whereasvif the.water-.falls4 lower than'ndi-' "l cated 1 Ait will stand W'holly Within the' f deeper portion ofthe oistern. As thus constructed the operation of cles'iiir-A L' now cleans out all the sediment that'v mayf have accumulated,l as the wall P has prevented any Aor ,it rom'pas'sing'into the space 'F. I. Moreover, the exact locatlon of the filter wall l? renders it'possible'for'hirn when'standin'rg. upon the raised portion R to clean the upper. side of the-filter wall fso'astoremove therefrom such particles' as have adhered thereto.

It is'.quite within thescope f this inven-g.` tionthat the filter Wall'fP shall be removablaf or that itmaybe made'of other material than; porous brickgorthelike although-'I referthe* atter.

3. The oom ination With a oistern having a surrounding Wall and mouth, 'a true depressed bottom, and a raised. and substantially fiat bottom, the two portions of the bottom" occupying about equal arts of the area of the oistern; 'of a porous iiiter wall extending fromthe corner between said portions of the bottom obii uely upward to the wall of the oistern and, ividin its interior into s aces for unfiltered and tered Water, an inet into the s 'ace for the uniiltered Water, and an outiet rom the opposite space,

4. The combination with a cistern having al surrounding Wall. and 'a eontraeted mouth,

a true depressed bottom, and a raised and substantially flat bottoni, the tWo portions of the bottom occupying, about equal arts of the area of the oistern; of, a filter Wa i eX- tending from the raised ortion of the bottorn obliquely to the Wal of the eistern near its 'mouth, an inlet directed downward onto Athe raised portion, and an outlet taken from a point near the bottom of the depressed portion.
